PADLOC K.

SPECIFICATION forming part of Letters Patent No. 484,895, dated October25, 1892.

Application filed July 16, 1392.

To all whom it may concern.-

Be it known that I, EDWARD A. JUDD, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented a certain new Improvement in Padlocks, ofwhich the following is a specification.

My invention relates to improvements in padlocks for bicycles,carpet-bags, and other uses; and the chief objects of my improvementsare simplicity and economy of construction and general efficiency of thearticle.

In the accompanying drawings,Figure 1 is k a front elevation of mypadlock with the free end of the chain disconnected therefrom. Fig. 2 isan enlarged front elevation of my padlock with the front half of thecase, the front tumbler, and holding-dog removed. Fig. 3 is a like viewof the same with the holding-dogin place and the swinging lock-bolt heldback thereby, and Fig. 4 is a like view with both the tumblers and dogremoved.

I construct the case of two parts A and B, the general form of saidparts being the same. In the confronting edges of these parts I formnotches or recesses in which to secure a T- head 5 for the attachment ofthe chain 6. The opposite end of this chain is provided with ashouldered head 7 for being engaged by the swinging lock-bolt 8. Thepadlock-case is provided with a circular recess or opening 9 at a pointdiametrically opposite that in which the T-head is received. Theswinging lockbolt 8 is of ordinary construction and is provided with aspring 10 for forcing it into engagement with the shouldered head 7. Itis also provided with the usual fence 11 for being engaged by theordinary tumblers 12 and the holding-dog 13. The tumblers are acted uponby a spring 14 to force them into ongagement With the fence when notlifted by other means. I prefer to employ two of these tumblers 12, oneupon each side of the holding-dog 13. This dog 13 is provided with aSerial No. 440,205. (No model.)

spring 15 for forcing it in the reverse direction from that of thetumbler-spring and said holding-dog is also provided with anupwardly-projecting portion 16.

By inserting the key and lifting the tumblers the swinging bolt may beswungoutwardly into the position illustrated in Fig. 3, and as soon asit reaches this position the holding-dog 13 under the influence of itsspring will be forced upwardly to hold said swinging bolt in itsretracted position, as shown in said Fig. 3. The holding-dog in snappingup to this position will bring its projection 16 against the inner endof the shouldered head 7 and force the same out of the padlock.

In order to lock the padlock, the chain is passed through the parts tobe fastened and the end forming the shouldered head 7 pushed into thepadlock, and in so doing its end will strike the projection 16 and pushthe holdingdog downwardly far enough to release the swinging bolt, sothat it will snap into the position shown in Fig. 2, where it willengage the shoulder of the shouldered head for locking the chain Withinthe padlock; but at the same time the tumblers will engage the fence 11,as shown in Fig. 2, so as to positively hold the swinging lock-bolt inengagement until it is again released by lifting the tumblers with theproper key.

I claim as my invention The combination of the shouldered head 7, theswinging lock-bolt 8, its tumbler 12 for holding said lock-bolt inengagement with said head, and the holding-dog 13 for holding said boltout of engagement from said head, substantially as described, and forthe purpose specified.
